UNITED. STATES PATENT OFFICE SCOOP LOADED Ernest B. Newell, RileyCounty, Kane. Application November 25, 1940, Serial No. 366,986 6Claims. (01. 214-140) This invention has to do with a vehicular scoopingmachine wherein a scoop is lowerable into a loading position in which itis loadable pursuant to advancement of the machine and subsequentlyelevatable to facilitate transportation of the load to a remote placefor dumping.

An object of the present invention is the provision of an improved scooploading machine of simple rugged construction including a scoop upon abeam that is pivotal within a vertical plane for lifting and loweringthescoop respectively between carrying and loading positions, and amanually controlled clutch for establishing a driving connection with atraction wheel of the machine for pivoting said beam.

Another object of the present invention is the provision of a scooploading machine in which a pivoted beam in support of a scoop upon itsfree end is raised and lowered by a crank axle which is clutchable by amanually controlled clutch to a traction wheel on a main bearing thereoffor rotation therewith.

Another object of the present invention is the provision 'of a scooploading machine as the foregoing wherein there is latch means forreleastl'cally adjustable scoop at the front of a longitudinal frame andlaterally disposed frame extensions at the rear thereof for theattachment of draft animals.

A still further object is the provision of a scoop loading machineincluding a longitudinal frame with a pair of laterally and closelyspaced support and traction wheels at the front of such frame, a crankaxle connectible for rotation with said wheels and having a throwbearing therebetween for lifting a scoop, draft extensions proiectinglaterally at the rear of the frame, and dirigible wheels respectivelyupon said extension and spaced apart more distantly than the tractiouwheels.

These and other desirable objects encompassed by and inherent to theinvention will later appear.

Fig. 10 is a vertical sectional view taken on the line l0lil of Fig. 1.

Referring now to the drawings and particm larly to Figs. 1 and 2, themachinewillbe seen to comprise a longitudinal frame 20 including a pairof side rails 2i and 22, a front cross member 23, a back cross member 24of which the ends project laterally beyond the main part of the frame,and an intermediate cross member 25. The just recited parts of the framemay be made of any sufficiently strong rigid material as wood or steeland maybe secured together by any standard means. Spacer blocks B aresecured between the cross piece 23 at its ends and the side rails 2| and22. I

A pair of support and traction wheels 26 and 21 are freely rotatableupon the end or main bearing sections 28 and 29 of a crank axle 30,which bearing sections are joumalled in bearing members It and 32secured upon the under sides of the longitudinal frame members 2! and 22by bolts 33; see Figs. 3, 4 and 5. Thus the wheels 26 and 21 support thefront end of the frame 20 irrespective of the rotative position of thethrow bearing section 34 formed by the central portion of the crankaxle.

The back end of the frame 2|! is dirigibly carried by casters 35 and 36within swivels 31' and 38 which are mounted beneath the ends of thecross piece 24. The swivel 3'! is provided with an arm 89 which isconnected to the back end of a foot actuated cross arm 48, Fig. 10, by atie rod 4|. The front end of said cross arm is operably connected withan arm 42 on the swivel 38 by a tie rod 45. In Fig. 10 the cross arm 45is shown fixed to the lower end of a spindle 44 of which the upper endis fixed to the lower end of a pin 45 rotatively disposed in the crosspiece 24. Left-hand and right-hand foot pedals L and R are integral witha base plate 45 and thisplate is non-rotatively associated with theupper end of the pin 45. The Just described connectlons between thepedals L and R and the castors 55 and 85 enable an operator to pivotthese castors for guiding the vehicle in a manner well understood, whilesitting upon a seat 41 carried by a standard 48.

Draft animals can be hitched to single trees 49 and 55 for propellingthe machine and in manipulating the machine they may be guided, in theusual manner, in the direction the castor wheels 95 and 55 are turned bymeans of the foot pedals L and R.

The machine includes a scoop in which the load is picked up and carried.Such load may consist of solid or loose earth, rubbish, fertilizingsubstances or any scoopable material. The scoop is forwardly directedsince it is mounted upon the front end of a beam generally designated 52and presents a bottom cutting edge 53 forwardly while in the scoopingand carrying position. A pair of brackets 54 are secured to the backside of the scoop 5| and are pivotally connected with diverging legs 55and 55 of the beam 52 by pivot pins 51. There is also a locking stud 58secured upon the back wall of the scoop and having a latch portion 59thereon cooperable with a latch member 55 as shown in Figs. 3, 4 and 5for maintaining the scoop in the loading and carrying position. Saidlatch member 55 is upon the end of. a rod 5| which is axially slidablewithin a spring chamber 52 containing a spring (not shown) which actsupon the rod 5| in a manner constantly urging said rod backwardly. Thisrod 5| extends backwardly along the upper side of the member 55 of thebeam 52 where it is pivotally connected with the upper end of an arm 53which is fixed upon an end of a rod 54 that. is rotatively attached tothe frame cross piece 25; see Figs. 1 and 6. An arm 55 is fixed upon theopposite end of the rotatable shaft 54 and the upper end of this arm ispivotally connected with a rod 55 of which the back end is pivotallyconnected with the lower end of a hand operated lever 51. It will beseen that the operator by grasping the upper end of the lever 51 forpivoting this lever counter-clockwise about a fulcrum support 58therefor will cause the rod 5| and the latch member 55 to be movedforwardly to disengage the lug 59 and thus permit the scoop 5| to pivotby the force of gravity downwardly about the pivot pins 51 into thedumping position.

The members 55 and 55 of the beam 52 are secured together at their backends where the beam is pivotally attached to the frame by a pivot pin 59mounted in a pair of spaced-apart blocks 59a which are suitably securedto the frame cross member 25. The beam 52 is pivoted upwardly about saidpin 59 for elevating the scoop 5| from the loading position illustratedin Fig. 3 to the carrying position illustrated in Figs. 4 and 5 byconnecting the crank axle 35 forrotation with the traction wheels 25 and21 while the vehicle is being advanced. When this rotation of the crankaxle occurs the throw bearin section 84 thereof is moved upwardlythrough an arcuate path while bearing against the undersides of the beammembers 55 and 55 and thus lifting the beam and the scoop.

Clutches are associated with each of the traction wheels 25 and 21 forconnecting these wheels with the crank axle, and inasmuch as theseclutches are of similar construction a detailed description is given ofonly that clutch associated with the wheel 25, the clutch beingillustrated in Figs. 8 and 9. Referring now to these two figures, 8 and9, the hub 15 of said wheel 25 will be seen to have secured thereto theweb portion 1| of a. drum 12, in this instance by means of a pluralityof bolts 13. The inner periphery of the flange 14 of the drum isprovided with a series of circumferentially spaced notches 15. When theclutch is disconnected the wheel 25 and the drum 12 rotate freely uponthe main bearing portion 25 of the axle 35.

A second drum 15 has a hub portion 11 secured non-rotatively to the axle85 by one or more keys 18. Journalled within the web 19 of the drum 15is a short shaft 55 which has arms 8| and 52 fixed upon opposite of itsends. A spring 53 has one end hooked about an apertured ear 84 and itsopposite end hooked within an aperture 55 within a head 85 upon the endof the arm 82 whereby the shaft 85 and the arms 8| and 82 are normallyheld at a clockwise limit of oscillative movement, Fig. 8, in which thearm 52 bears against a stud 51 which is also upon the drum web 19. Thelower end of the arm 8| is connected by a cable 88 with the lower end ofan arm 59 which is fixed upon a cross shaft see Figs. 1 and 8. Alsofixed upon this cross shaft is a hand lever 9| which is withinconvenient reach of the operator. The cross shaft 95 is mounted forrotation upon the frame members 2| and 22, there being an arm 59' uponthe right side of the frame member 22 that corresponds to the arm 89 anda cable 88' leading from the arm 59', Fig. 2, to the clutch mechanism,similar to that shown in Figs. 8 and 9 but associated with the tractionwheel 21.

Assuming that the vehicle has been advanced while the scoop 5| is in itsloading position illustrated in Fig. 3 and has thus become charged witha load, the operator will cause the scoop to be elevated by grasping andpushing forwardly upon the lever 9| whereby the arm 82, Figs. 8 and 9,will be pivoted to carry the head 85 thereon into one of the notches 15upon the drum 12 whereupon this drum which rotates with the tractionwheel 25 will impart through the arm 82 a component of force causingrotation of the drum 15 and of the bearing section 28 of the crankshaft35 to which it is keyed. Simultaneously the clutch associated with thewheel 21 will similarly establish a driving connection between saidwheel and the crank axle whereby said axle is caused to rotate with thetraction wheels.

Upon the throw-bearing section 84 reaching the elevation in which thescoop has been raised to the carrying position, such throw-bearingsection will engage an automatic latching device generally designated inFig. 3 and which will hold the axle in this rotative position untilmanually released as will be described presently. Also upon the axle 35being rotated sufilciently for elevating the scoop 5| into the carryingposition, a pin 93, Fig. 8, which is anchored in "he machine frame, willbe engaged by the arm whereby this arm is pivoted clockwise anddislodged from the notch 15 in which it had been disposed. Acorresponding pin 93', Fig. 5, disengages the clutch'associated with thetraction wheel 21. Thereupon the wheels 26 and 21 rotate freely upon themain bearing sections of the crank axle while the latch mechanism 92maintains the scoop in the carrying position.

Referring now to Figs. 3, 4 and 5 the latch mechanism 92 will be seen tocomprise fixed jaw members 95 upon the frame cross piece 23 and amovable jaw member 95 which is pivoted at 91 to a bracket 98 which isfixed to the underside of said cross piece. A contraction spring 99connected between an extension I 01 a plate IOI upon the upper side ofthe cross piece 23 and a tail portion I02 of the pivoted jaw member 96constantly urges said member 95 to rotate counterclockwise. The lawmember 96 is provided with a striking cam surface I03 which, whenabutted by the throw bearing portion 94 when the latter is movingupwardly, will cause the jaw 95 to pivot clockwise for admitting saidbearing section into the space between the jaws as illustrated in Fig.4. Thereupon the spring 99 will cause the jaw 96 to pivotcounter-clockwise for carrying the point I04 beneath and behind thebearing section 34 while the arcuate sections I05 and I05 of the jawmembers retainingly clasp said bearing section. With the loaded scoopthus supported and with the wheels now freely rotatable upon the axlemain bearings 28 and 29 the machine may be taken to any desired placefor dumping.

Manual release means for the latch mechanism 92 includes an aperturedear I01 upon the upper side of the movable jaw 96 and a cable I08 whichpasses successively over rotatable spools I09, H0 and III, Figs. 5, 'land 1 and forwardly to an apertured ear II3 upon a hand lever I I 4. Itwill be seen that when the operator grasps the lever I I4, which ispivoted to the frame by a pin I I5, and moves this lever backwardly thatthe cable will exert an upward force upon the movable jaw 96 and thusrelease the crank portion of the axle whereby it may swing downwardlybe: cause of its own weight and the weight of the scoop 5I and the beam52 thereon. In lowering the scoop 5| from the carrying position to theloading position the speed at which the crank axle is allowed to rotateis govemable by brakes of which one is illustrated in Figs. 8 and 9.This brake includes a flange as IIB upon the drum I6 and a brake shoeIII which is pivotally connected with the machine frame by a pin H8. Thelower end of this brake shoe I I9 is connected by a cable I I9 with aportion of the arm 89 above the cross shaft 90. A cable II9corresponding to the cable H9 is connected between the upper end of thearm 89, Figs. 1 and 2, and a brake shoe II'I' similar to the brake shoeII! but associated with the assembly at the hub of the wheel 21.

rest, the latch mechanism 92 released by drawing the lever I I4backwardly, and the brake shoes II I and 1' applied to the drums IGandI9 by pulling backwardly upon the lever 9| to regulate the speed atwhich the scoop descends. when the edge 53 reaches the ground the scooppursuant to further lowering will pivot counterclockwise, Fig. 3, aboutthe pins 51 sufliciently to permit relatching of the latch 60 with thestud 58, preparatory to receiving another load.

It should be understood that the invention is not limited to thespecific form or environment herein illustrated, but extends to otherarrangements, details and structures falling within the spirit of theinvention.
